Generate Large Test Files in Windows 8

Introduction

In this article we are going to explain how to quickly generate large test files in Windows 8. Never download another 100mb test file or waste time searching for a large file. Sometimes we need a large file fast to test data transfers or disk performance. Windows 8 includes a utility that allows you to quickly generate a file of any size instantly.

Some steps to create a test file for the Windows 8 Desktop.

Step 1

First of all we have to move to the Start screen window of Windows 8.

 

Step 2

Then move the cursor on the bottom-right of the window screen and click the search box which is helpful to search in Windows 8.

 

Step 3

Then in the search box type "command prompt" and right-click on the command prompt from the right sidebar.

 

Step 4

Then click "Run as administrator" from the down sidebar.

 

Step 5

Then we see an administrator command prompt on the Windows 8 Desktop.

 

Step 6

Run the following command: fsutil file createnew <file> <size in bytes>

This command will create a 1GB file on the Windows 8 Desktop.

fsutil file create new c:\users\temp\desktop\1gb.test 1073741824

 

Step 7

Then right-click on the test file and select properties and then check the size of the test file.

 

Some reference data to help input the size of the file in bytes:

1 MB = 1048576 bytes.

100 MB = 104857600 bytes.

1 GB = 1073741824 bytes.

10 GB = 10737418240 bytes.

100 GB = 107374182400 bytes.

1 TB = 1099511627776 bytes.

10 TB = 10995116277760 bytes.
